Supports radial loads through a single row of balls running in deep grooves of the inner and outer ring, with contact seals fitted on both sides to keep the raceways protected. This deep groove ball bearing, 62204-A-2RSR from FAG, has a bore diameter of 20.0 mm, an outside diameter of 47.0 mm, and a width of 18.0 mm, weighing 0.13 kg. The cage is a sheet steel type JN, and the limiting speed is rated at 9400 1/min. Radial internal clearance falls in the CN (Group N) range, giving the running accuracy expected for standard fits without added preload. The two-sided rubber sealing arrangement retains grease inside the bearing and blocks contaminants from entering, so the bearing runs maintenance-free once mounted and does not require external relubrication during service life.
